1, the teaching order of many teachers is pairing, listening to the reverse order and naming, which means that students can pair these items and listen to the reverse order as an aid when naming their teaching.

2. If you use pairing, you can display three cards on the desktop and then give the students an apple card. The instruction is "Put the apples together". After the students were paired, the teacher immediately picked up the paired apples and asked, "What is this?" Because the instruction given by the teacher involves apples, students will say apples.
